Document Summary
It"s the cross-sectional area that"s important for how strong the bone can be. Consider a short pillar (thicker) vs a tall pillar (thinner), both of the same mass. The shorter one will be able to withstand the weight that it takes to snap the tall pillar! If you scale just the regular dimensions (length, diameter) with body mass, there"s positive relationships. As the thing gets heavier, the bones are getting longer and the diameters are larger. Relationship between skeletal mass vs body mass; relationship x1. 09 while it"s expected to be. Skeletons in large animals are more fragile than those in small animals! Recall the regular chicken vs 6000kg chicken example (can a t-rex run fast?). Being so small, a chicken is better able to withstand faster running. As you run, you place a lot of pressure on your bones. If you"re too huge, your bones are gonna need to be ridiculously huge to handle it.
